The right option is; d popcorn salt

A mixture is a substance that is formed when two or more different substances are combined in a way that no chemical reaction takes place between the substances. In a mixture, each of the constituents maintains its chemical identity, and the mixture can be separated back to its normal constituent. Examples of mixtures are salt and pepper, water and salt etc.

If you were to take all of the DNA from all of the chromosomes in your body and stitch them all together into one continuous lin
sergiy2304 [10]

Answer:

152.88 solar unit.

Explanation:

The haploid genome content of the human cell is  3.3 x 10⁹ bp but the human cell is diploid.

So, the content of the diploid cell = 2 ×3.3 x 10⁹=  6.6×10⁹ bp/cell.

1 cell contains DNA = 6.6×10⁹ bp/cell.

10¹³ cell DNA content =  10¹³ x  6.6×10⁹ = 6.6 x 10²² or 6.6 x 10¹⁹ kilo base pairs.

1 kilobase pair of DNA = 340nm = 340 × 10⁻⁹m.

6.6 x 10¹⁹ kilo base pairs of DNA = 340 × 10⁻⁹ × 6.6 x 10¹⁹ = 2244 x 10¹⁰m.

1 meter= 6.2 ×10⁻⁴ miles.

2244 x 10¹⁰m = 6.2 ×10⁻⁴ × 2244 x 10¹⁰m = 13912.8 ×10⁶ miles.

1 solar unit = 9.1 x 10⁷miles.

Then 13912.8 ×10⁶ miles = 13912.8 ×10⁶ miles/ 9.1 x 10⁷miles = 152.88 solar unit.

Total human DNA in terms of solar unit = 152.88 solar unit

Thus, the answer is 152.88 solar unit.
